I have a list of tasks in my database with different start dates and required finish dates organized in two columns. For each column, I want to create a new column to capture the "MAX", "MIN", "Average" date by Task ID for scheduled dates after the current year. Keep in mind that the dataset has millions of records that date back to 10 years but I want to create a Gantt Chart to capture the "WORKDAY" duration for the current year only.

Please create a calendar table, create a flag column if the date is workday. Then you can use count workdays.
You want to calculate the "WORKDAY" duration for the current year only, so use the following formula to create a calendar table.
Calendar = CALENDAR ( DATE(2017,1,1), MAX ( FactTable[Finish date] ) )
Then add a flag column using the formula.
WorkingDay_Mark = VAR WeekDayNum = WEEKDAY ( Calendar[Date] ) RETURN ( IF ( OR ( OR ( WeekDayNum = 1, WeekDayNum = 7 ), RELATED ( Holidays[Date] ) <> BLANK () ), FALSE (), TRUE () ) )
Finally, calculate the count of workdays.
WorkingDay_Num = COUNTROWS ( FILTER ( Calendar, AND ( AND ( Calendar[Date] >= FactTable[Start date], Calendar[Date] <= FactTable[End date] ), Calendar[WorkingDay_Mark] ) ) )
If you have any other problem, please feel free to ask.
I am trying to figure out how to calculate working days between dates power query by hour, day, month, and year in a single month. Also is the table field is blank for any of these fields, and want power query to return a blank cell for the duration
Could you share a little more detail about how you did this in Power Query? I have ben getting an error message for each time I try. I copied and pasted the formula into the Query Editor but it didn't work.
